1. Offensive Tackle -- USC is extremely thin at the tackle position. The only true pro style tackle the Trojans have is Kevin Graf. While Aundrey Walker will anchor the right tackle spot, I wouldn’t be surprised if by his junior or senior season he isn’t moved down to guard like Deuce Lutui was in 2005. However, the only way this can happen is if the Trojans can lock up at least one more top tackle in this year’s recruiting class.
2. Defensive tackle -- With the losses of Christian Tupou and DaJohn Harris, the Trojans arevthin and inexperienced at defensive tackle. On paper, the most likely replacements for the two seniors will be redshirt freshman George Uko and either one of the two true freshmen, J.R. Tavai or Antwaun Woods. Although Uko and Woods should hold their own against the run, the Trojans need a true pass rusher who can get to the quarterback and create pressure up the middle.
3. Safety -- The safeties will be a strength for the Trojans this season. T.J. McDonald and Jawanza Starling will both be seniors and should pick up right were they left off last season. However, the depth at the position is shallow when looking towards the future. The Trojans did pick up a couple of transfers, but with the bulk of backfield being seniors, USC still needs more top talent at the position.
4. Running Back -- Before every season, the problem at the running back spot seems to be how they are going to share the carries. But this season it seems to be more along the line of “who else is there to share the carries with?” This is the first time in a good 10 seasons that the Trojans have had this problem and with Curtis McNeal graduating after this season, the Trojans need a true feature back. USC did get Jahleel Pinner and although I really like this pick up, I see him playing fullback.
